Facebook Messenger has reached version 1.9, and includes some UI changes, as well as some new features. Version 1.9 also brings the app into direct integration with the main Facebook app, for the first time.

The new version of Messenger sports full emoji support, one-click access to friends' Facebook Timelines, as well as indications marking whether or not a friend is 'active'. Version 1.9 also includes a "last active" indicator, telling you when the last time your friend was online. You can grab the iOS version from the App Store, and the Android version from the Play Store.
